JOHN CARROLL, OF DOVER, OHIO, ASSIGNOR TO THE REEVES MANUFACTURING. GOM-PANY, GF DOVER, OHIO, A CORPURATION' OF OHIO FRAIVIE FOR COATING FAILSAND THE LIKE gOriginal applicationfiled November 2, 1928, Serial No.316,754. Divided. and this application filed September 21, 1929. i

The invention relates to the coating of pails, buckets and otherarticles with zinc, tin or other coating materials and more particularlypractice, either formed from sheets which have been previously coatedwith zinc or tin;

or the articles are formed of blacksheets and then dipped in the moltenzinc, tin or other coating material for coating the same.

The cheaper grades of such coated articles are usually formed fromsheets which have been previously coated withzinc or tin, for thereasonthat a thin coating may be obtained by first galvanizing ortinning thesheet in the usual galvanizing or tin pot provided with rolls whichengage opposite sides of the sheets and squeeze the surplus metaltherefrom.

However, it has been found by experience that, particularly in the useof galvanized or zinc coated sheets, the coating breaks or cracks informing the articles of the previously coated sheets. Also, it is notpossible in so forming the articles to provide sufficient r I substantally on the line 4l4, Fig. 3.

coating at the seams to properly protect the same against rust orcorrosion in use.

For this reason, it is customary, under present practice, to make thebetter grade of such articles from black sheets and then dip the formedarticle into the molten zinc or tin for coating the same. The metalcoating thus formed upon the article properly coats the seams of. thearticle and is not subjected to i tially' vertical rod lO'arranged to beconnectedat its upper end-to the conveyer'or the like and supporting theframe .at'it s lower sheets.

Although it is knownthat attempts have been made to produce machines formechanically coating formed pails, buckets and the like and some fewpatents havebeen obtained upon such machines, there is no suchapparathereon;

tus, to applicants knowledge, which has ever been capable of'commercialuse.

Therefore, all such articles, which are first formed of black sheets, orthe like, are dipped by hand into the molten zinc or tin in order tocoat the same. This hand dipping is not only very slow and expensive butdoes not permit of a uniform coating of metal being applied throughoutthe entire surface of the article and usually results in acoatingconsiderably heavier than is necessary, thus materiallyincreasing the cost of the'finished coated article. V

The obj ect'of the present improvement is to provide an apparatus forcoating buckets, pails and other receptacles with zinc, tin or othercoating material; and for applying a uniform coating of the desiredthickness upon the articles; and for properly covering the seams with asubstantial coating ofthe metal. An embodiment of the invention isillustrated in the accompanying drawings, in which v i Figure l is afront elevation of one of the improved frames or holders to which theinvention pertains, showinga pail supported Fig. 2, a top plan view oftheframe with Fig. 3, aside elevation of the frame showing'the pailthereon; and.

Fig. 4, a section on an enlarged. scaletaken from a conveyer or the'likearranged to pass the frames, and the pails or other articles carriedthereby,-through the coating'material.

Each frame is provided'with a substanend. r

The normallyhorizontal frame is carried at the lower end of the rod '10and comprises a pair of "diverging arms 11' connected at their outerends as by the bar 12, to the center of which is fixed the rearwardlyextending finger 13.

In the crotch of the arm 11 may be provided a lug 14, adapted to supportthe bot tom portion of a pail or bucket indicated at 15," while theupper portion of'the pail rests upon the arms 11 which may be providedwith the knife edge lugs 16, the finger 13 extending into the open endof the pail and engaging the interior thereof at a point spaced from thetop of the pail, as best shown in Figs. 3 and 4.

' This finger 13 is preferablyprovided on its under side with a knifeedge 17 for engagement with the interior of thepail, as

V illustrated in said figures.

In placing the pails in the frames, the seam, indicated at 18, islocated at the bottom, as best illustrated in Fig. 4.

lhe pails are placed on the frames, as above described, and the framesare lowered into the coating material to submerge the pails therein andmove therethrough, the movement preferably being laterally of the pails.

As each pail is raised from the coating material, the frame is'preferably tilted backward to flow the coating material uniformly overthe same and then forward, pouring the excess of coating material fromthe pail and in this manner giving an extra heavy coating upon theinside of the seam 18.

I claim:

' 1. In an apparatus for coating pails and the like, a frame adapted tocarry a pail and the like, and including a pair of substantiallyhorizontally disposed, diverging arms for supporting the pail inhorizontal position and a finger carried by the outer end portions ofthe arms'and adapted to project inside of the pail.

2. In an apparatus for coating pails and the like,a frame adapted tocarry a pail and 5 the like, and including a pair of substantiallyhorizontally disposed, diverging arms for supporting the pail inhorizontal position and a. finger carried by the-outer end portions ofthe arms and adapted to project inside of the pail and having a'knifeblade lug for bar and adapted to project inside ofthe pail and having aknife blade lug for contact with the inner surface of the pail.

5. In an apparatus for coating'pails and the like, a frame adapted tocarry a pail and the like, and including a pair of substantiallyhorizontally disposed, diverging arms, a lug at the crotch of the armsfor supporting one end of the pail, and knife blade lugs near the outerend portions of the arms for supporting the other end portion of thepail.

6. In an apparatus for'coating pails and the like, a frame adapted tocarry a pail; and the like, and including a pair of substantiallyhorizontally disposed diverging arms, a lug at the crotch of the armsfor supporting one end of the pail, knife blade lugs near the outer endportions of the arms for supporting the other end portion of the pail,and

a finger carried by the outer end portions of outer end portions of thearms for supporting the other end portion of the pail, a crossbarconnected to the outer ends of the arms, and a finger carried by thecrossbar and adapted to project inside of the pail and having a knifeblade lug for contact with the inner surface of the pail.

In testimony that I claim the above, Ihave hereunto subscribed myname.
